Complete question 1.

Answer:

28 rabbits

Step-by-step explanation:

From the statement, you can write the following:

d+c+r= 126

d=dogs

c= cats

r= rabits

Then, you have that there are 13 cats and that three fourths of the remaining animals are dogs:

c=13

d=(126-13)*(3/4)= 113*(3/4)= 85

Now, you can isolate r, to find the number of rabbits:

r=126-d-c

r= 126-85-13

r= 28

According to this, the are 28 rabbits.

Answer:

10.89

Step-by-step explanation:

Circle:

C = TTD

C = TT(6.6)

C = 20.73451151

C = 20.73

Triangle:

A = bh/2

A = 6.6(3.3)/2        6.6/2=3.3

A = 21.78/2

A = 10.89

Shaded Region = 10.89

Step-by-step explanation:

p(A|B) = p(A and B) / p(B) =(1/5) / (2/9) = 0.9

The probability that event A occurs is 5/8 , the probability that event B occurs is 2/9 , and the probability that events A and B both occur is 1/5 . The probability that A occurs given that B occurs is 0.9.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

The probability that event A occurs is 5/8

The probability that event B occurs is 2/9

The probability that events A and B both occur is 1/5.

So, The probability that A occurs given that B occurs

P(A|B) = P(A and B) / P(B)

          = (1/5) / (2/9)

          = 0.9

Answer:

A. 24°

Step-by-step explanation:

ABC is 85° which is the whole angle. DBC is a part of ABC and is 61°. If we do 85-61=24. The answer would be 24°.

PLZ MARK BRAINLIEST!!!

If m ∠ABC=85° and m ∠DBC=61° then m  angle ABD=24°. Hence the option A is correct.

An angle is the figure formed by two sides of a figure ,  sharing a common endpoint, called the vertex of the angle.

From the given figure we can conclude that ∠ABD=∠ABC-∠DBC.

We have been given that m ∠ABC=85° and m ∠DBC=61°

∠ABC=85/m and ∠DBC=61/m

Put in the above equation

∠ABD=∠ABC-∠DBC

∠ABD=85/m-61/m

=24/m

we have been find m ∠ABD so we have to multiply 24/m by m is 24°.

Hence the value of m angle ABD=24 degrees.

Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles

Answer:

Triangles A and C are congruent.

Step-by-step explanation:

Congruent triangles are when two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The total of the angles of all triangles is 180, so then add all the angles then subtract that number from 180.

A: 110+30=140 (180-140=40)

B: 30+45=75 (180-75=105)

C: 110+40=150 (180-150-30)

Since Triangles A and C have the same angles, then they are congruent!!!

Answer: The answer is 580

Step-by-step explanation: you first do the front side which is 20 x 10 which is 200. You multiply 200 by 2 since the front and back are the same.

then you move on to the sides.

the bottom of the side is 3. The height is 20. 3 x 20 is 60. Since there are 2 sides, you will do 60 x 2 which is 120.

now we move on too the top. The width of width is 3. and the length is 10. 10 x 3 is 30. Since the bottom is also the same, you do 30 x 2. You add all the numbers.

So 400 (from the front and back) + 120 (from the sides) + 60 ( from the top and bottom)

thiss all equals 580. sorry if it is a bit confusing I just understood it too. I am 14 trying to get math a year above me.

Answer:

£800

Step-by-step explanation:

For this question we need to utilise decimal multiplier. Since this is a decrease question to work out the decimal multiplier you have take 100 away from the percentage and then divide by 100. If this was an increase question then we would had to add 100 to the percentage and then divide by 100. Since the question is asking for the price before the decrease we are going to have to divide the multiplier by the price so,

⇒ Work out the multiplier by taking 100 away from the percentage and then dividing by 100

→ 100 - 20 = 80  ↔  80 ÷ 100 = 0.8

⇒ The multiplier is 0.8, now we have to divide the multiplier by the price

→ 640 ÷ 0.8 = 800

The price of a washing machine was decreased by 20% to £640. The price before the decrease was £800

M = 29

27.31838095 = n

16.8511209 = p

Step-by-step explanation:

M = 180 -33-118 = 29

We can use the rule of sines

sin A          sin B           sin C

------------ = ---------- = ------------

a                  b               c

sin 118          sin 29        

------------ = ----------

n                  15              

Using cross products

15 sin 118 = n sin 29

Divide by sin 29

15 sin 118 / sin 29 = n

27.31838095 = n

sin 33          sin 29        

------------ = ----------

p                  15              

Using cross products

15 sin 33 = p sin 29

Divide by sin 29

15 sin 33 / sin 29 = p

16.8511209 = p

Answer:

Base = 13in

Height = 17in

Step-by-step explanation:

Step-by-step explanation:

height of a parallelogram = 4 times more than it’s base

Let height = H

Base = B

H = 4 + B

area of the parallelogram = 221 in²

area of the parallelogram = base × height

221 = B × H = B × (4+B)

221 = 4B + B²

B² + 4B - 221 = 0

Using almighty formula to find B

See attachment for explanation

From the calculation:

Since the dimension of the parallelogram can't be negative, B = 13in

Height = B + 4 = 13+4

Height = 17in

Answer:

Base = 13 inches

Height = 17 inches

Step-by-step explanation:

The formula to find the area of a parallelogram = Base × Height

Let's represent Base = B

Height = H

From the question, the height is 4 times more than the Base

Height(H) = B + 4

Area = 221 square inches

Therefore, area of a parallelogram = Base × Height

221 sq in = B ×( B+4)

221 sq in = B² + 4B

B² + 4B - 221 = 0

We would solve the quadratic equation using factorisation method. Hence,

B² + 17B - 13B - 221 = 0

(B²+ 17B) - (13B - 221) = 0

B(B + 17) - 13(B + 17) = 0

(B + 17) (B - 13) = 0

B + 17 = 0

B = - 17

Or

B - 13 = 0

B = 13.

From the above calculation, since B = Base

B = -17 inches Or 13 inches

The base of a parallelogram cannot be negative, hence , The Base of the Parallelogram = 13 inches.

We are told that the height of the Parallelogram is 4 times more than the Base. This was represented but the equation

B + 4 = H

Since B = 13 :

13 + 4 = H

Height(H) = 17 inches.

Therefore, The base of the Parallelogram is 13 inches while the height of the Parallelogram is 17 inches.

Answer:

Small scooters = 6

Large scooters = 4

Step-by-step explanation:

Let S represents small scooter and L represents large scooter

The cost of a small scooter is £80

Mathematically,  the cost of S number of small scooters is

80S

The cost of a large scooter is £130

Mathematically,  the cost of L number of large scooters is

130L

The total amount spent on both scooters is £1000

Mathematically,

80S + 130L = 1000

So we have 2 unknowns and only 1 equation. Therefore, we have use trial and error method .

Trial and Error Method:

80S + 130L = 1000

80S = 1000 - 130L

S = (1000 - 130L)/80

Let’s suppose they bought 1 large scooter

S = (1000 - 130(1))/80

S = 10.875

Number of scooters cannot be in fraction so 1 doesn’t work

Let’s suppose they bought 2 large scooter s

S = (1000 - 130(2))/80

S = 9.25

Number of scooters cannot be in fraction so 2 doesn’t work

Let’s suppose they bought 3 large scooter s

S = (1000 - 130(3))/80

S = 7.625

Number of scooters cannot be in fraction so 3 doesn’t work

Let’s suppose they bought 4 large scooters

S = (1000 - 130(4))/80

S = 6

So that means they bought 6 small scooters and 4 large scooters.

Similarly, other combinations for scooters don’t work since they yield either fractional value or negative value which cannot be correct.

Therefore, the only possible combination of small and large scooters is

6 Small scooters

4 Large scooters

Verification:

80S + 130L = 1000

80(6) + 130(4) = 1000

480 + 520 = 1000

1000 = 1000 (satisfied)
